ABSTRACT:
In the disclosed camera and power winder arrangement, a power winder winds the film and contains a rewinder. A detector responds to rewinding movement of the film past a predetermined position, and a control circuit responds to the detector's sensing that the film has stopped moving past the predetermined position by braking the film rewind source.
